M3534RT Boost Boost Regulator Regulator Ride-Thru Ride-Thru Power Power Protection Protection for for 11 -- 67 67 hp hp Drives Drives Undervoltage Solutions for AC Drives - 50% 2 Seconds Sag Bonitron’s Model M3534RT series of DC Bus Ride-Thru Modules provides protection from line voltage sags for 208-460VAC Adjustable Speed PWM Drives that use a fixed rectifier and DC bus. Many drives claim to have ride through capability, such as auto restart or kinetic buffering, but they are not able to maintain complete control over the motor as called upon by a critical process during undervoltage power disturbances. The majority of AC line voltage sags that occur in three-phase distribution systems have a magnitude (decrease from nominal voltage) of less than 50% and duration of less than .5 seconds. Model M3534RT provides sufficient ride through capability to handle these types of voltage sags by temporarily storing energy in an inductor and releasing it back into the drive’s DC bus using maintenance free IGBT switching technology. This allows the drive to “ride through” these events, MAINTAINING MOTOR SPEED and TORQUE, without experiencing drive shutdown. The M3534RT connects in parallel with drives so it does not decrease system reliability. Modules are tested and certified to exceed Semi-47 requirements.
Features • Electronic switching scheme - Does NOT use batteries or capacitors • Simple 5 wire hook up directly to drive • Parallel connection • Very low standby power losses (less than .2% of rating) • Built in test with optional display and activity counter • External DC input
Advantages • No maintenance - 50% sag 2 second spec does not decrease over time • Easy implementation, easy retrofit • Ride-Thru system failure will not affect process • No heat losses to remove • Ability to activate system while on line, monitor status and record events • Can add outage protection as need arises
Benefits • Minimizes down time - stops major production losses • Low installation and operating cost • Does not decrease drive system reliability • Gain confidence in system’s ability to maintain control over process • Adding on caps later can make implementing outage protection easier on budget • Allows connected drive to far exceed SEMI-47 specifications
